To all whom it may concern:

Be it known that l, HENRY G. VOIGHT, a citizen of the United States,residing at New Britain, county of Hartford, State of Connecticut, haveun'ented certain new and useful Improvements in Snap-Flasks for Molders'Use, of which the following is a full, clear, and exact description.

.l-lv invention relates to improvements in molders' flasks of the copeand nowcl type, and more particularly to snap flasks, SID-Called. Thesedevices comprise two companion upper and lower sections termedrespectively the cope and the nowel.

With these sections top and bottom boards are used, but since theseboards constitute no part of this invention, they need not be shown ordescribed.

The object of my invention is to provide a simple. exceedingly durableand effective construction. aiming at cconoin of manufacture and maximumservicea ility. The construction also has the advantage of lightness.strength and comparative inexpensive- In the drawings Figure 1 is aperspective view of one section kin this instance the nope") of a snapask (partly broken away) and constructed to embody m inven F i 2 1s arelatively enlar ed detail View of u guide-pin and socket for the copeand Bowel. Fig. 3 is a vertical cross-section of Fig. 2. Figs. 4; 5 and6 are respectively sectional views of the same parts showing threediffcrent positions of adjustment. Figs. 7, 8 and 9 are respectivelysideelevations of the Kiwis shown in Figs. 4, 5 and 6, said parts ingseparated and broken away at the center. Fig. 10 is a pers iectire viewof one corner of one section of t 1e flask illustrating details ofconstruction and a slightly modified method of connecti Ir the cornerconnestions as compared wi t h that illustrated Fig. 11 is a View of theunder side of the part shown in Fig. 9.

Since the cope and noweP sections of the flask correspond substantiallyin construction, detail dcscri tion of one section is sufiicient for afull un crstanding of my invention. One of these sections carries" asocketand the other a coacting whereby in use said cope and may be heldtogether in roper o rative relation. Both sections opt-he flas are madefrom sheet or wrought metal, and each seei are interlockin guide-pin"the divided corners,- in this particular intion preferably comprises aplurality of overlapping plates constituting the side walls. in thedrawings 1 have shown the side walls as composed of three late to wit.an upper plate 1, a lower p ate 2, and an intermediate plate 3 (seeFigs. 4 to 9). These plates are correspondingly 'rooved or corn ated lon'itudinally on their abutting sin aces, so that said corrugations willregister or interlock one with another when the parts are placedtogether. By means of these corresponding corru tions, the manufacturermay make each o these three parts of a standard size, and by giving aproper pitch or spacing to the grooves or corrugations, may assemble thesame so as to provide (with one standard set of plate? a flask sectionof several difl'erent sizes. or example, as shown in Fig. 4, the minimumsizeor depth is provided. In this figure, it will be observed that the,two ed es of the parts 1-2 practically abut. In fig. 5 they are spacedapart the width of one corrugation, increasing the depth of said flasksection to a. oorres onding extent. In Fig. 6 the two edges 0? the parts1-2 are spaced apart the width of two corrugations, furnishing a flasksection of correspondingly greater depth. It should not be assumed thatthese variations in size are accomplished by the user (the molder) butthe are rather an important and valuable exp ient of the manufacturer,who, in making said flasks, may, by the adoption of this standard arra-nement of parts. readily produce flasks of ifierent dimensions. Thesesections 1. 2 and 3 are secured together at the corners. which cornersmay be and preferably are suitably mitered. and around which cornersreinforcements 4 are secured, these corner reinforcements beingsuit-ably shaped to close the corners of each flask section to preventleakage.

."|-5 are top and bottom plates, which are secured respectively to a topflan e 1 of each part- 1 and the flange 2 of one part 2.

All the parts may be secured togct icr by any suitab e fastenmgs, suchas rivets 6-43. Each flask section is preferably divided at two 0 positecorners, one line of division being indicated at 7 1.

cvices provided for stance the interlockin" device 8 being in the formof a hook rigi y secured to one side of the flask section, while 9represents a manuall operable hook pivotaily connected at 9 tot 1eadjacent side of the flask section, said hooks 5 and 9 coiiperating tointerlock and hold the two sections of the flask in proper operativerelation for use. bearing reinforcements will be, of course, provided tosupport the hooks 8 and 9, these being rigidly secured to the sectionsof the flask which respectively carry said parts. It may be assumed thatthe flask section shown in Fig. 1 is the cope, and to that end, followinthe usual practice, a guide-pin is provided on this part. The ide-pin isof novel construction in that it, like the preceding parts, may beformed of sheet metal of a proper gage to withstand the strain of useand wear and tear. indicated at 10 and is struck up from wrought metalin such a manner that its rear T side appears as channeled, each sideedge of each guide-pin being turned back, as at 10, and out along its ede to conform to the cor rugated walls of a acklate 11. The corrugationsof the back-p ate 11 preferably correspond to the corrugations in theside wall of the nowel section, so as to permit said part to beelfectively secured thereto. In the 11 of t preferred construction, theback-plate e guide-pin is provided at its front side with reinforcements12-42, each of Suitable 3 This guide-pin is which are slotted at 12,said slots passing 5 through the back-plate to receive an attachin screwbolt 14, which passes through a suitable opening or perforation in theside wall of the co where said guide-pin is to be muted. y providing aslotted bolt pasage for each guide-pin fastening the guide-pin 10 may bereadily adjusted up or down. The guidein construction is shown on arelatively en arged scale in Fi c. 2 and 3andthe method of fastening thegui epin to the back-plate 11 is best seen in Fig. 3, in which it willbe seen the rear edge of the portion 10 of each guide-pin is providedwith int 1 rivet extensions 1010" which are p s through perforations inthe backplate 11 and are upset or riveted over to rigidlv andpermanently secure the pin 10 to the backlate 11. The top of theguide-pin may be c osed in by a plate 15 secured by inte 'ral rivets 10formed at the upper edge of tie parts 10.

The nowel section, which, as already explained, may corres nd to thecope section already described, is provided with a suitable socket toreceive the guide-pin 10. The socket construction is best seen in Figs.2 and 3, and may comprise tin-angular strucknp wrought metal portion 16channeled at its back to embrace the guide-pin 10, and havingturned-back rear edges 16* secured by integral extensions 16 to aback-plate 17, corresponding in function to the backplate 11 of theguide-pin. This back-plate bolt,

may have reinforcements 18-18 perforated or slotted and designed toreceive screw bolts or other equivalent fastenings 19, whereby saidback-plate and the socket proper 16 may be secured to the non-clsection. it?" is a friction spring, which may be struck in from the sideof the socket 10 to frictionally press against the guidepin 10 whencontained therein, to hold said parts snugly in frictional contact.

In Fig. 10, I have shown a slightlv modified form of cornerreinforcement. In this view, it will be seen that the ends of the sidepieces All of the flask section are not mitered, but are squared on,while the corner reinforcement C is corrugated throughout, saidcorrugations corresponding with the corrugations in the side sections.-\B to iegister and interlock with the same. These parts C are rivetedthereto so as to make a permanent rigid structure. This figure willserve merely to illustrate that I comprehend that various modificationsmay be made in the construction without departing from the spirit andscope of the invention, said figure illustrating only one of the manymodifications that may be adopted.

In manufacture, it will be seen that many economies are attained, sinceby the production of sets of standard parts the manufacturer may,without additional cost, produce a line of flasks of varying sizes andyet of comparatively the same minimum weight. By the employment ofcorrugated metal two advantageous ends are attained, to wit,greatstrength at a minimum of weight and expense, and a capacity fororiginal adjustment to various standard sizes.

In use, the advantage of lightness and great strength and durability arecons icuous. Again, in use the corrugated wa of the flask sectionspermit the sand to be packed in in such a manner as to interlock ill thecorrugations, thereby more firmly holdin it in place than in the case ofa plain at sided wall against which the sand must adhere rather thaninterlock. in, in use, the danger of injury to the flas by coming incontact with molten metal is eliminated. Again, the structure is sorigid and firm that the danger of warping is avoided. Inasmuch asdevices of this kind are subjected to the most severe uses, being Hungabout the foundry, resistance to injury from this cause is anotheradvantage strikingly characteristic of the construction describe-d.

So far as the use of the terms cope and nowel are em loved in thespecification or claims, it shou d be understood that said terms areused interchangeably, for I appreciate that to a very substantial extentthe advantages of my invention might be obmined if either one of saidsections were constructed in accordance with my invention and the othersection constructed in a different manner. Hence. in order to secureadequate protection. it should be understood that from the standpoint ofconstruction, a
